I have a use case where I don't always want a default value in any of my fields, but the CalendarDatePicker widget was forcing one upon me.
I've created my own version of the widget (I'm really becoming a fan of widgets) but I think this is a common enough use case for it to be available in base.py. Once trac is back up I'll post a patch, but in the meantime if anyone wants the code, feel free to email me. Regards, Lee
